If you read carefully the syntax for the SELECT from
http://developer.postgresql.org/docs/postgres/sql-select.html
you will see that the limit clause in the first select is not allowed
there. Don't forget the LIMIT applies to the entire result set not the last
select making up the union.
So in short, that is how it's supposed to work so there's no need to document
it.
